Photo taken on Aug 18, 2017 shows the stamp on one of the works of Argentine artist Martin Mazia in Buenos Aires, capital of Argentina. Mazia, who now teaches Chinese calligraphy and painting as well as the Chinese language, was introduced to the Chinese art forms more than 15 years ago and has exhibited his works in many countries including Argentina and Colombia. Those works are serving as a cultural link between Latin America and China. [Photo/Xinhua]
